ABSTRACT:
A free floating mount for the holographic disc of a scanner which enables centrifugal force developed by rotation of the disc to bring the disc into perpendicular relationship with the axis of the disc motor shaft and prevent disc wobble, comprising, a first self aligning couple composed of a pin and socket for supporting the disc on the end of the motor shaft, the shaft and disc having coaxial bores therethrough; a tensioning cable assembly extending through the motor shaft and disc bores, one cable segment of the cable assembly being attached to a retaining ball receivable in a socket in the disc, the retaining ball and socket forming a second self aligning coupling; a second cable segment at the opposite end of the cable assembly having a retaining ball attached thereto receivable in a socket in the motor shaft end and forming a third self aligning coupling; an extension spring interconnecting the first and second cable segments to form the cable assembly whereby the motor shaft and disc are biased through the second and third self aligning couplings into engagement through the first self aligning coupling to drivingly mount the disc on the motor shaft.
